This results in the production of cement clinker, an intermediate product in the manufacturing process. The cement clinker emerges from the kiln, is cooled, and then finely ground to produce the powder we know as cement. The fuels combusted to heat the kiln account for about 40% of cement-manufacturing emissions.
Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical …
Articles like this one can provide a lot of useful material. However, reading an article or two is perhaps not the best way to get a clear picture of a complex process like cement production.

The main part of the manufacturing process of clinker takes place in the kiln. The stages in the kiln phase are as follows: Evaporation of free water: A pressure above atmospheric is required to vaporize the water from the slurry mixture of raw materials.
The high cost of making Portland cement inhibited its utilization in concrete, but three important developments in the manufacturing process lead to modern Portland cement: (a) development of rotary kilns, (b) addition of gypsum to control setting, and (c) utilization of ball mills to grind clinker and raw materials.
A brief description of the manufacturing of bricks and four stages i.e., preparation of soil, moulding of bricks, drying of bricks and burning of bricks.
Cement, a fundamental component in construction, is produced through a complex manufacturing process involving various stages and raw materials. The process begins with extracting raw materials through quarrying or …
The entire manufacturing process in a modern plant is now controlled through a microprocessor based programmable logic control system to maintain a consistently uniform quality of cement and a high rate of production.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

The following is a wet process of cement manufacturing step-by-step guide, 1. The raw limestone from quarries is first crushed into small size fragments.
When described in broad terms the cement manufacturing process is relatively straightforward. In addition to the processes outlined, other processes include mining (quarrying), primary and secondary crushing and transport of raw materials, pre-blending, storage, loading and discharge of powder and clinker, and bagging of cement.
Quite a few wet process kilns are still in operation, usually now with higher-tech bits bolted on. However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower.
The raw cement ingredientsneeded for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller pieces of about 6 inches. Secondary crushers or hammer mills then reduce …
